Application filed March 11, 1914. Serial No. 823,867.

To all whom it may concern Be it known that I, DANIEL BnnNNAN, residingat VVoodlawn, in the county of Beaver and State of Pennsylvania, acitizen of the United States, have invented or discovered certain newand useful Improvements in Charging-Ladles, of which improvements thefollowing is a specification.

The object of my invention is to provide for steel manufacturing plantsa furnace charger for putting molten metal into furnaces, andparticularly adapted to be used in Charging-Ladles, of whichimprovements the following is a specification.

In large open hearth plants a plurality of furnaces are usually placedside by side and are charged and drawn successively. In order toincrease the production of steel from each furnace it has become thepractice in several works to put a suitable quantity of molten metalreduced in a Bessemer converter into the open hearth furnace. A largeamount of silicious or acid slag comes with the metal from the Bessemerconverter. If this slag be allowed to enter the open hearth furnace, itmust be neutralized by adding a suitable agent, such as lime. Myinvention is directed to overcoming the necessity of adding largequantities of lime for the purposes indicated. For charging the openhearth furnaces with bessemerized metal, I provide a charger which maybe readily moved from one furnace to another and which is so constructedthat the metal may be admitted through the furnace door by means of aspout attached to the charger, suitable means being provided to preventthe slag from entering the furnace.

The preferred form of the charger is illus' trated in the accompanyingsheets of drawings, which form part of my specification.

Figure 1 shows a side elevation of charger and a sectional view of afurnace into which it is adapted to charge molten metal; Fig. 2 avertical sectional View of the charger shown in Fig. l but to enlargedscale; Fig. 3 a plan view of the charger; and Figmla sectional elevationtaken on the line IV-IV, Fig. 3.

In the several views like numerals are used to designate like parts.

The charger comprises a ladle 1, a support or pedestal 2, spout 8 andstopper 4. The ladle may be of any desired form, and is provided with arefractory lining 5 and with trunnions 6, whereby the charger may beengaged by a crane and moved from one furnace to another. The pedestal2, which is secured to the bottom of the ladle 1 by means of bolts 7,may be made of cast iron, and is of such height that, when the chargeris resting on the floor in front of a furnace, the spout 3 will extendthrough the door thereof, as shown in Fig. l. The spout 3 extendslaterally from the ladle and is socured to the side thereof, as by bolts8, there being an orifice 9 in the side wall of the ladle leading to thespout, the arrangement being such that the molten metal. will flowgradually into and through the spout, rather than impinge in a streamon, and possibly destroy, the refractory lining 10 thereof. The stopper1 is preferably operated and controlled by suitable means secured to theoutside of the ladle and within easy reach of a workman. As shownherein, the stopper is attached to an arm 11, secured to a rod 12,pivotally mounted in suitable brackets 13 and 13 :xtending laterallyfrom the ladle. Secured to the outer ends of the rod 12a1'e a pair ofcountciaveighted arms Ll, which in their alternate positions, hold thestopper arm 11. in open or closed positions.

When in operation, the charger is placed on the floor in front of thefurnace chamber 15, as seen in Fig. 1, the spout 3 extending through thefurnace opening 16. To prevent the molten metal from flowing into thefurnace while it is being poured into the ladle 1, the stopper 9 may beheld in oriliceclosing position; or, what is more desirable, the orificemay be closed by a plugof wood or some refractory material, for examplea crucible stopper ('5. c. a stopper made of black lead). After the slaggathers on the top of the molten metal placed in the ladle, the orificemay be opened permitting the metal to flow into the furnace until theslag is seen, at which time the stopper l is brought to closed position.The slag may then be dumped from the ladle and the charger moved, bymeans of a crane, to the next furnace to be charged, the operation beingthere repeated.

I claim as my invention:

1. A movable charger for putting molten metal into furnaces, comprisinga ladle, a support secured to the bottom thereof, a spout secured to theside of and extending laterally from the ladle, an orifice through theside wall of the ladle leading to the spout, and means secured to theoutside of the ladle for closing said orifice to control the flow ofmetal therethrough.

2. A movable charger for putting molten metal into furnaces, comprisinga ladle, a support secured to the bottom thereof, a

spout secured to the side of and extending laterally from the ladle, anorifice through the side Wall of the ladle leading to the; spent, and acounterweighted arm pivoted to the outside of the ladle and providedWith 10 a stopper adapted in one position of said my hand.
